Answer:
Volume of a cone = 847.8 cm³
Step-by-step explanation:
Volume of a cone = 1/3hπr²
π = 3.14
radius, r = 9 cm
height, h = 10 cm
Volume of a cone = 1/3hπr²
= 1/3 * 10 * 3.14 * 9²
= (1 * 10 * 3.14 * 81) / 3
= 2543.4 / 3
= 847.8
Volume of a cone = 847.8 cm³

What is the area of the shaded sector?
O 411 units?
O 8 units?
O 16 units
O 2011 units?
The area of the shaded sector is [tex]8\pi[/tex] square units
The area of a sector is calculated using:
[tex]A = \frac{\theta}{2}* r^2[/tex]
So, we have:
[tex]A = \frac{\pi}{2}* 4^2[/tex]
Evaluate the exponent
[tex]A = \frac{\pi}{2}* 16[/tex]
Evaluate the quotient
[tex]A = 8\pi[/tex]
Hence, the area of the shaded sector is [tex]8\pi[/tex] square units

The ratio of the energy of a photon of x-rays of wavelength 0.05 nm to that of a photon of visible light of wavelength 500 nm is
Answer:
1 : 10000
Step-by-step explanation:
Energy of a photon of x-rays of wavelength = 0.05 nm
Energy of a photon of visible light of wavelength = 500 nm
The ratio is given as;
0.05 : 500
1 : 10000
Therefore, ratio of the energy of a photon of x-rays of wavelength to that of a photon of visible light of wavelength is 1 : 10000

The area of square C is 100 square units and the area of square B is 64 square units. What would be the area of square A?
Answer: The area of square A is 28 square units because the area is decreasing by 36 and the angles on each side is decreasing by 9
Step-by-step explanation:
100 divide by 4 sides = 25
64 divide by 4 sides = 16
28 divide by 4 sides = 7
Evaluate: log6 1,296
Answer:

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12Side = 23 unitsStep-by-step explanation:
STU is an equilateral triangle. And:
ST = 2x - 1SU = 5x - 37TU = x + 11All sides are equal. Then take one pair and solve for x:
2x - 1 = 5x - 373x = 36x = 12Substitute x to find the side length:
2x - 1 = 5x - 37 = x + 11 = 23Charles lost 4 of the 10 dollar bills that his parents gave him for his birthday. What percentage of his dollar bills did he lose?

Find the 14th term of the geometric sequence 2, 6, 18,
The geometric sequence is starting with 2 and multiplying by 3 every time. We can get the rule of this sequence by...
If 2 is a_0, 6 is a_1, 18 is a_2, etc.
a_n=2*3^n
For the 14th term, which is a_13, the value is 2*3^13.
Using a calculator because I'm too lazy to calculate 3^13 sorry, we can get.
3188646
The required 14th term will be 3188646 in the given geometric sequence.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
The geometric sequence is given in the question, as follows:
2, 6, 18,...
We have to determine the 14th term of the given geometric sequence.
As per the given geometric sequence,
The first term a = 2.
The common ratio r = 6/2 = 3
14th term = arⁿ⁻¹
Substitute the value of a = 10, r = -2, and n = 12 in the formula,
14th term = 2(3)¹⁴⁻¹
14th term = 2(3)¹³
14th term = 2(1594323)
14th term = 3188646
Thus, the required 14th term will be 3188646.

Sam has already worked for 27.7 hours this week. He washes cars, and can wash a car in 2.5 hours. He wants to work over 60.2 hours this week.
The question is incomplete ; we could calculate the least number of cars he can still wash for the week expressed in inequality form.
Answer:
x > 13 ; 13
Step-by-step explanation:
Given that :
Anticipated work hour for entire week = 60.2 hours
Hours worked = 27.7 hours
Rate of car wash = 2.5 per hour
Hours left to work for the week :
60.2 - 27.7 = 32.5
Hours left / unit rate of car wash
32.5 / 2.5
= 13
Hours worked +( hours left * unit rate) > anticipated hours
27.7 + 2.5x < 60.2
2.5x > 60.2 - 27.7
2.5x > 32.5
x > 32.5 / 2.5
x > 13
Hence ; Sam could still wash over 13 cars this week
